England Application August 10, 1934, Serial No. 739,359 In Great Britain August 16, 1933 6 Claims. (01. 242-158) This invention relates to cable and rope winding appliances, such as winches and hoists and has for its object the provision of means to facilitate coiling or laying of the cable around the winding drum so as to prevent over-riding and snagging and prevent damage to and eliminate the wear due to feeding the cable on to a drum which has only one movement, 1. e. that of rotation, it being well known that bad winding results 20 each convolution thereof, or, in other words, for

each revolution of the drum, so that better winding results. when the cable reverses and coils back over that previously laid, a complete revolution of the drum 25 is allowed before the return movement commences so as to ensure that the cable fills up the entire length of the drum before winding back over itself.

Broadly, the invention consists in mounting the 30 winding drum loosely upon an axle so as to be capable simultaneously of rotation and of a transverse axial reciprocatory movement in relation to a fixed feeding eye or the equivalent, the total transverse movement of the drum being approxi- 35 mately equal to the length of the winding barrel,

whilst the rate of transverse movement is adjusted so as to amount to a distance equal to the thickness of the cable for each revolution of the drum. 40 The invention is illustrated in the accompanying drawings wherein:-

Figures 1, 2 and 3 are respectively a front elevation, an end view and a longitudinal crosssection showing diagrammatically the essential working elements of appliance and Figures 4 and 5 are front and end elevations of a winch in accordance with the invention suitable for attachment to a motor tractor.

In an embodiment of the invention, a flanged 50 drum I is slidably mounted upon a horizontal axle 2 which extends between a pair of end frames 3, the length of the axle 2 being such as to permit a sliding movement thereof of the drum I of a distance not less than the distance 55 between the drum flanges. The peripheries of At each end of the drum movement the flanges l of the drum I are provided with teeth which mesh with a long gear pinion 5 extending between the side frames 3 and arranged parallel to the drum axle 2. This pinion 5 derives a rotary motion through intermediary gear- 5 ing 6 from a suitable power shaft I and thus effects rotation of the drum I throughout its transverse reciprocatory movement. This latter movement of the drum I is effected by a slider crank motion. This motion consists of a crank disc 8 10 rotatably mounted on a fixed axle 9 located ap proximately midway between the side frames 3 of the appliance, the said crank disc 8 having a projecting pin III which slidably engages within the slot I I of a slide I2 which is supported upon guide rods I3 arranged parallel to the drum axle 2. The slide member I2 has sidewardly projecting arms I4 which are adapted to contact with the flanges 4 of the drum I so that when the crank disc 8 rotates, its pin I0 moves the slide I2 from side to side and the slide I2 in its turn effects a reciprocatory movement of the drum I. The crank disc 8 has peripheral teeth I5 which engage with a worm gear I6 driven at suitable speed through gearing I! from the pinion 5. The shaft of the pinion 5 is provided with a brake drum l8.

The arms I 4 of the drum reciprocating means are of less length between their extremities than the distance between the flanges 44 of the drum, therefore, the initial reverse movement of the drum reciprocating means is idle with respect to the drum to provide the result heretofore pointed out, namely at each end of the drum movement, when the cable reverses and coils back over that previously laid, a complete revolution of the drum is permitted before the return movement of the drum commences so as to insure the cable filling up the entire length of the drum before winding back over itself, thereby providing evenly stacked layers of cable on the drum.

The cable is delivered to the drum I through a fixed feeding eye I9 or the equivalent, such as between a pair of freely mounted rollers, said feeding eye or the like being disposed above the crank disc 8.

Figures 4 and 5 of the drawings illustrate the embodiment of the foregoing invention in one of its commercial forms, namely a construction suited as an attachment for a motor tractor. Clearly, other forms of embodiment may be re- 5 sorted to, but the figures above noted serve to illustrate the range of embodiment.

I claim:

1. A winch of the class described including side frames, ashaft mounted between said side frames,

a gear pinion journalled in the side frames and having gear teeth extending from end to end thereof, a winding drum mounted to rotate and a gear pinion journalled in the side frames and slide on the shaft, gear teeth associated with the drum for continuously meshing with the teeth of the gear pinion during the rotary and sliding movement of the drum, means for reciprocating the drum, and cable guiding means fixed with reference to the drum.

2. A winch of the class described including side frames, a shaft mounted between said side frames, a gear pinion journalled in the side frames and having gear teeth extending from end to end thereof, a winding drum mounted to rotate and slide on the shaft, gear teeth associated with the drum for continuously meshing with the teeth of the gear pinion during the rotary and sliding movements of the drum, said meanscomprising a slide having means for engaging the drum to shift it back and forth between the side frames, a power driven crank disk having a sliding pin engaging with the slide, and cable guiding means fixed with reference to the drum.

3. A winch of the class described including side frames, a shaft mounted between said side frames,

having gear teeth extending from end to end thereof, a winding drum mounted to rotate and slide on the shaft, gear teeth associated with the drum for continuously meshing with the teeth of thegear pinion during the rotary and sliding movements of the drum, said means comprising spaced guide rods spanning the side frames, drum reciprocating means mounted on the rods, a power driven crank disk operatively connected with said reciprocating the drum including spaced guide rods, a shiftable member mounted on said rods and having means for engaging alternately with opposite flanges of the drum, a guideway in said shiftable member, a fixed axle shaft, a crank disk mounted on said fixed axle shaft, power means for rotating said crank disk, 2, member carried by the crank disk and slidable in said guideway whereby rotation of the disk will reciprocate the drum shifting means, and cable guiding means fixed with reference to the drum.

5. A winch of the class described, including, side frames, a shaft mounted between said side frames, a gear pinion journalled in the side frames and having gear teeth extending from end to end thereof, a winding drum mounted to rotate and slide on the shaft, gear teeth associated with the drum for continuously meshing with the teeth of the gear pinion during the rotary and sliding movement of the drum, cable guiding means fixed with reference to the drum, and means for reciprocating the drum, said means comprising guide means supported by the side frames, drum reciprocating means mounted on said guide means and including lateral arms ,of less width than the distance between the drum flanges to permit the said means to have an initial idle movement in both directions of movement with respect to the drum, and a power driven crank disk for moving said drum reciprocating means.

6. A winch of the class described, including, side frames, a shaft mounted between said side frames, a gear pinion journalled in the side frames and having gear teeth extending from end to end thereof, a winding drum mounted to rotate and slide on the shaft, gear teeth associated with the drum for continuously meshing with the teeth of the gear pinion during the rotary and sliding movement of the drum, cable guiding means fixed with reference to the drum, and means for reciprocating the drum, said means including means whereby each initial reverse movement of said means for reciprocating the drum is idle with respect thereto to permit the initial coil of each superimposed layer of cable to overlie the last coil of the previous layer.
